Derp Gun - A gun that causes a lot of damage with one shot, usually having a very long reload time and low penetration. Usually associated with short, High-caliber guns that load HE. Artillery guns are not considered derps (e.g. the 'derp gun' on the USSR tank KV-2).
The joy of the derp gun, is like the joy of s*x, but with explosions.

For people that dont know the stages of derping.

Derping is very common now a days where you screw up something or you just come off as plain stupid.
There are four stages of derp:
The first stage in where the majority of people are at and are a non derp where they may screw up once in a while and just reset back to normal at the beginning of each day.
The second stage of derp is a Common derp and are usually found in ditches with a shovel as they are boarder line derp usually found with IQ's lower than 100 and derp from 5 to 15 times a day.
The third stage is where you fail at most things in life expessially english and dont know how to spell and may derp from 15 to 50 times a day. This stage is called a Pro-Derp.
The fourth stage is a Royal derp it has nothing to do with the queen but whoever is at this stage should get a medal of some sort because they derp at least 50 or more times a day.
"I hate These stages of derp because it always ends up that I am a common derp at at the end of the day."
"It's okay Ron, just next time don't drop out of grade 10"

"Chef is gone, so let me introduce myself. I'm your new cook, Mr. Derp!" (DUN DUUUUUN)
